Basically I want my last itemrenderer to do something different if it's the last itemrenderer. I thought I had this licked with the code: if(rowIndex == dataProvider.length) since I don't have a scrollbar and display all itemrenderers at once in the datagrid I thought that the dataprovider's length and the total number of rows would work, but this is not the case, sometimes there are 1 or 2 more itemrenderers than displayed?
Re: [flexcoders] spark DataGrid
Thanks, I actually decided to just rebuild the entire thing using spark lists. DataGrid seems very problematic.

[flexcoders] Spark Datagrid - Show all rows using requestedRowCount variableRowHeight=true
I have a Flex Spark Datagrid that has variableRowHeight set to true. I also have the requestedRowCount set to the length of the dataProvider. So, in theory the rows shown should be the same number in the dataprovider(Arraycollection). However, the problem is that due to having variableRowHeight=true and some rows being multiline, in some instances, all of the rows are not getting shown. Suggestions on how I can fix this issue? Thanks, in advance.

[flexcoders] Spark Datagrid / IGridItemEditor.save() issue when using the tab key
I have problem with the IGridItemEditor.save() method.
According to the docs for save()...if the data isn't valid, then the data isn't
saved and the editor is not closed.
So I setup an example to test this, and its seems ok. However, once I enter
valid data and hit the Tab key, I expect the next column to contain the
itemEditor. Instead its the column after that (which isnt correct).
Maybe i'm going about this the wrong way, so any advice would be great.

[flexcoders] Spark Datagrid selectedItem question
How would I go about making the datagrid.selectedItem the ONLY editable row? A bit like making individual columns editable by setting GridColumn.editable. Thanks BH
